can't edit database via userform (Error in Range)

Hi,

I've created a userform to search data in a database and then edit it.
I found the original userform in the Net and then adapted it to my needs.

I cant't make the userform run:
run-time error '1004':
method 'Range' of object '_Global' failed.

I've looked at the code lots of times but i can't seam to find the error.
Can anyone help?

I send the workbook to make it easier.

Thanks

Thank's...i suspected that was it, but i didn't knew what to put in
